High-Q whispering-gallery mode lasing from nanosphere-patterned GaN nanoring arrays [PDF]
, 2011 A hexagonal-close-packed ordered array of nanorings was fabricated on GaN with a modified nanosphere lithography process. The spheres initially served as etch masks for the formation of closed-packed nanopillars.

Concentric GaAs nanorings growth modelling
Физика и техника полупроводников, 2018 AbstractThe nanostructures formation process using the droplet epitaxy technique was investigated by Monte Carlo simulation. The simulation was fulfilled for two-dimensional and three-dimensional geometry substrates. The nanostructures morphology dependence on the growth temperature was presented.

Helical edge states in silicene and germanene nanorings in perpendicular magnetic field
, 2017 Due to nonzero intrinsic spin-orbit interaction in buckled honeycomb crystal structures, silicene and germanene exhibit interesting topological properties, and are therefore candidates for the realization of the quantum spin Hall effect.

A molecular dynamics investigation of the mechanical properties of graphene nanochain
, 2012 In this paper, we investigate, by molecular dynamics simulations, the mechanical properties of a new carbon nanostructure, termed graphene nanochain, constructed by sewing up pristine or twisted graphene nanoribbons (GNRs) and interlocking the obtained ...

Breaking the Symmetry in Molecular Nanorings
The Journal of Physical Chemistry Letters, 2016 Because of their unique electronic properties, cyclic molecular structures ranging from benzene to natural light-harvesting complexes have received much attention. Rigid π-conjugated templated porphyrin nanorings serve as excellent model systems here because they possess well-defined structures that can readily be controlled and because they support ...

Phase Diagram of Magnetization Reversal Processes in Nanorings
, 2009 We investigate magnetization reversal processes of magnetic nanorings. Using a recently developed efficient cartesian coordinates fast multipole method, magnetization switching phase diagrams are constructed for such structures. We find that the dominant
